I think you can try, depending how arsey you want to be you can:
- Say you disagree its in his best interests for such a long phased introduction to school and suggest it is disability discrimination
- Speak to the LA SEN Officer and tell them about the part-time timetable. The LA has a responsibility to ensure your child receives fulltime education. If it can't be provided in a school the LA has a duty to provide it 'otherwise than in school' under section 19(1) Education Act so you could for eg insist on a home tutor for the hours not in school
- Point out you have a legal duty under section 7 Education Act 1996 to make sure your child attends school full-time: Duty of parents to secure education of children of compulsory school age.
The parent of every child of compulsory school age shall cause him to receive efficient full-time education suitable?
(a)to his age, ability and aptitude, and
(b)to any special educational needs he may have,either by regular attendance at school or otherwise"
The LA can provide additional funding to school via the Statement of SEN so he can attend fulltime.
See also Children, Schools and Family Act 2010 s.3 which suggests LAs can only arrange a part-time timetable for medical reasons, not because of SEN/ disability. [sometimes there is a phased reintegration into school after an exclusion but thats not your situation]
- Tell them what you want to happen and say if you are asked to collect him during school hours outside this then you will want that registered as a formal exclusion and require a letter giving reasons why he has been excluded.
- Suggest he comes fulltime (or your option) and see how it goes rather than school assuming he cannot cope.
- Point out due to his SEN he requires more teaching than the other children not less!
I would suggest you talk to IPSEA for advice or use their email service to check law etc.
I would think if you ring the LA SEN Officer they would put pressure on school given he will be 5 before Sept.
The only issue may be that if he is on part-time timetable at time of statement review then you will be a good position to argue for more support.
He does not have to be in class all day he can have 'pullouts' in a quiet area with his 1:1, so they would need to have very strong arguments why he could not be on school premises.
But yes I think you are within your rights to drop him off at same time as other children and not to pick him up until end of school and if they are not happy they will have to formally exclude him.
